Chapter 10: Repair Welding^[1]

This article describes the repair of weld defects and failed structures. It provides information on three factors that must first be considered before attempting a repair, namely material weldability, nature of the failure that prompted the repair, and involvement of any code requirements. The article discusses the processes involved in welding process selection and the methods of preparing base metal for repair welding. It presents the guidelines for weld repairs of various ferrous (carbon steels, cast irons, and stainless steels) and nonferrous (for example, titanium) base metals.
